Kapa AI search results: font clipping, open new tab and labels

[mrjones-plip]

With a soon to be live move to using only Kapa AI for search, I think we should make some improvements:

• do not open a clicked results in a new tab. I think this is especially frustrating for docs search results - I'm on the docs site already, I don't need a new tab!
• "p" and "g" and "j" and "y" (anything that hangs below a line of text) get clipped. Tested on FF and Chrome, desktop and mobile:
  
• We helpfully label docs results and github results. we also have mystery results - these are all docs as far as I can tell. they should be labeled docs like the other docs results:
